Re:Duplicate SR7 records in an index

I unloaded the data area only. The index name is in the SR7, the SR7 is a
CALC record and the CALC key is the set name. I reviewed the Schema and
there was only one (1) set with the index structure stored in the index
area. I even re-compiled the Subschema and examined it with IDMSLOOK. Plus
remember that I rebuilt the index using the exact same subschema as the U/R.
After the index rebuild there was one SR7, then I immediately followed up
the index rebuild with the U/R and immediately after the U/R there were two
(2) SR7 records again in the index area.

I think that it has something to do with the EXTEND SPACE and the fact that
an SR7 is a CALC record? I have never had an index area that was EXTENDED
before; this is a first for me. I should have fixed it before the index
rebuild.
